Antennas like the DB8e are UHF only by design. You would need to add a separate antenna with VHF capability given the channel assignments used in your area.
Another point to consider, as the panels are adjusted away from the 0 degree position, this type of antenna will produce less peak forward gain. That's not a criticism, just the physics involved. In some cases, the DB8e and similar designs provide an elegant solution... But they aren't a one size fit's all solution.
In this case, I'd start with a single fixed aim antenna as suggested above. You then have the option to add a second, separate system if you want to chase down some additional signal options. A second system could be either fixed aim or rotating, you have a great deal of flexibility...
